There are a range of compositional approaches and techniques to consider when producing work of a sonic nature; from decisions about source material and location, to set-up configurations and sound diffusion. The presented case studies will examine approaches taken by the composer for indoor and outdoor spaces and discuss the artistic intention of each piece within a specified space. The case study examples will range from contemporary theatrical sound designs to sound art performance and audio-visual installations. Comparisons will be made between the various disciplines of sound art in relation to theatre sound in order to seek common ground and the suggestion of a sharing of practice.
